ESTIA - System Set Up
Please refer to the ESTIA Service Manual for a detailed description for
each of the controls / functions listed below
1. External room thermostat
Isolate the electrical supply to the ESTIA system and remove the cover to the electrical box
in the hydro unit
Install the room thermostat into the room to be monitored / controlled. Care must be taken to
ensure that the thermostat is installed in the correct position and away from the influences of
other external heat sources (sunlight, radiators etc.). Follow the thermostat manufacturers
installation instructions for correct positioning
Connect the room thermostat as to the TCB-PCBMO3E option PCB as shown in the diagram
above
In the hydro unit set DPSW 02_4 to ON
For HEATING mode:
Set FC1A to the required setting. This will set the maximum target water temperature of the
system when running in heating mode. This setting is particularly important
– if the heating
emitter used is under floor heating then damage may be caused to the floor surface if FC1A
is set too high
Set FC1B to the required setting. This will set the minimum target water temperature of the
system when running in heating mode
Set FC9D to the required setting. This will set the initial target water temperature of the
system, when the electrical supply is restored to the ESTIA system, when running in heating
mode
For COOLING mode:
Set FC18 to the required setting (only required if cooling mode is available). This will set the
maximum target water temperature, of the system when running in cooling mode
Set FC19 to the required setting (only required if cooling mode is available). This will set the
minimum target water temperature, of the system when running in cooling mode
Set FC96 to the required setting. This will set the initial target water temperature of the
system, when the electrical supply is restored to the ESTIA system, when running in cooling
mode
Replace the cover on the electrical box in the hydro unit and restore the electrical supply to
the ESTIA system
NOTE:
When the external thermostat is connected the end user will be unable to set any water
temperatures, for the space heating or space cooling functions, on the remote controller. The
system is controlled by the OPEN or CLOSED contact on the room thermostat.
